To aZZcOhomitmayconceTa g JEAN PARIs, J r;,- '{a citizen {of the United States, resid Be itknown that I, 'Auensrn ing in Bradfo'rd, county of McKean, and State of Pennsylvania, have invented a certain new and useful'Process of Separating the Lighter Oils from Crude-Petroleum or ,Coal Oil,of which the followingis specification. 7 I; p v

' This invention is a process: of separatmg the lighter oils from crude] petroleum or the process'is equally applicable to theitreatcoal oil,but, to avoid repetition, the invention WlllbG particularly described in con-,

c The drawing shows in elevation, more or v 1 less diagrammatically, the form of appara-' ms to which reference has "been made.

Referring to the drawing, the pipe A,

providedwith valve a, is the gas inlet, said pipe. connecting with a coil'B located in afcasingrb, nto hich'a cooling or heating medium, as circumstances require, may be "introduced through a pipe 6, and" drawn off through a pipe 6 thereby providing means vvhereby the gas may be heated or cooled. The'outlet pipe 0 from coil B leads to a compressor 0.

D is a source of crude oil,'the oil being drawn therefrom through pipe cl by pump E and forced through coil (2 located in casmg e, having an inlet 6? and an outlet e for a heating or cool ng agent, whereby said ml, 111 its passage through coil 6, i s

If desired, the oilmay be of a spray, but," in any event,.on1y suiiicient oilis introduced therein as will; be vaporized by the, gas. admitted to the-compressor when the latter is compressed. A small excess of "oil, however, W111 do no particularjharm.

The outlet 9 from the compressor, provided withfa valve ,9, leads to a separator 'or'trap F,-xvhere1n thewhe-avy residues or OllS are dropped out from the mixture.

Thereupon, the mixed oil and .gas, freed introducedinto the compressorin the form from the heavy products, passes through pipe it into condenser G, and thencethrough pipe 72, to condenser G. The lighter oils are separated or dropped out in condenser G, and the' nextlightcr' or lightest in con denser G. t that as many condensers may be used 111 series as are found necessary tocondense all the vapors carried by the gas.

The heavier or residuary oils which separate in tank F may be drawn through pipe 0, provided with valve 0, and pipe 29, provided with valve g9, into receivingtank H. If, however. any lighter oils are separated in tank F which it may be desirable to reuse, such oils may be againintroduced into the system through pipe 9, provided with Qvalve g, to coil 6, and thence to compressor C, as hereinbefore described. The lighter oils separatedin condensers G and G, respectively, may be drawn ofi through pipes r, 7', respectively, into receiving tanks 1,

It will be understood that the'system is supplied, wherever necessary, with" suitable check valves, such as s and s, thermometers such as 2% 25 t and a pressure gage such as a.

From the foregoing description of the apparatus coupled with the general statement given of my invention, the operation of the apparatus will be readily understood,

although it may be briefly summarized as follows,

The oil andgas having been introduced into compressor G, the mixture is compressed therein for the purpose, merely, of eifecting an intimate contact of the oil and gas, wherebythe latter absorbs or picks up the lighter constituents of the oil, whereupon the mixture passes into separator or traJ F, wherein the heavier oils are se 3a rated. The, gas, carrying the lighter oils in the form of vapor, passes through pipe 7'1v into condenser G, and thence through pipe 71; into condenser G, finally passing out of the system through pipe 7", or returned for reuse through pipe 11. The lighter oils which are condensed in condensers G and G, are drawn into receptacles I and I, for use as required.

lt'will be understood that, if desired, the

It will be understood, of course,

7 absorbed by said gas and; oil vapors may be com ningled or mixed before their intro'duction into compression cylinder C. i,

"As hereinbefore" stated,the gas may be either heated or cooled prior to its compression, and, if desired, the oil may "also be preheated. The oil and gas may be preheated separately, or together.

Itwill be understood that the precise op- V erations described may be varied within reasonable limits, as-will be apparentto those skilled in the art,- without departing from; the spirit or substance of the inven-K tion, and: that my invention is nothmited" to all of theoperations described, sincesome of the advantages ofv the invention maybe realized without carrying out thecomplete processdescribed. i

Having thus fully described-the inve n tion, what I, claim is new, and desire to secure by Letters Patent, 1s:
